The only caveat I would offer on this is to make sure you're using commercial brass in this process. The military brass has less internal capacity and tends to be a little harder. That's not to say it wouldn't fire-form to the AI shape, but it's not ideal for reloading purposes.

Also, its always a good idea to use new brass when fireforming. Older brass can develop splits rather quickly, depending on how many times reloaded. Once-fired brass would be OK.
